I've tested everything on it without any hickups, problems with previous versions (6.0.1.2 6.0.1.3 6.0.1.4) backup and sometimes hangups is solved in this one.

It includes a new menu item named "install zip from sideload" which can be used for installing a zip from your computer using "adb sideload 'path/to/zip'". It requires a newer adb, version 1.0.29 or higher.
